    Siemens Gamesa Blade Closeout Plates, Vestas & ZF Plastic Torque Tube
    2024/11/06
    This week on Power-Up, we discuss Siemens Gamesa's method for stabilizing wind turbine blades by installing closeout plates. Then Vestas and ZF's idea to replace the metal torque tube in the gearbox with a plastic piece, protecting from current. And finally, an Enercon patent for painting blades in an ombre pattern to lessen visual disturbances. Sign up now for Uptime Tech News, our weekly email update on all things wind technology.

Follow along with me, Allen Hall, and IntelStor's Phil Totaro, as we discuss the weird, the wild, and the game changing ideas that will charge your energy future. All right guys, our first idea is what's turbine blades, and it's an idea from Siemens Gamesa, and it In patent form, as they describe it here, it's what they call a novel approach to stabilizing wind turbine blades without the need for traditional trailing edge beam designs. But what they're really doing is they're installing closeout plates on the, between the aft spar and the trailing edge. So, This idea is pretty much making a wind turbine blade look a lot like an airplane wing, Phil. Philip Totaro: Yeah, especially like an older style airplane wing. So those that aren't familiar with the closeout plate, it's like a rib design that has this, vertical element at different longitudinal locations throughout the Kind of the, the max cord section and in inner portion with the exception of like the, the immediate root section of the blade. But it's, it's interesting to me, besides just the, the general concept here, the timing of this was fascinating to me because they filed for this patent back in April of 2024. And the patent has now published in October and the question Is, is this a potential fix to a problem? Is this what's this really doing? Allen Hall: Well, it's stopping torsion is what it's doing, Phil. It's preventing the blade from twisting too much, which makes me think of a couple of blades that I'm familiar with that have torsion problems. Joel? Joel Saxum: Well, if you look at the image here, so I've crawled around in quite a few blades doing RCA's and failures, and you're always looking for failure modes, so you start getting into a different mindset of when you're crawling around in them. But In multiple blades that I've been in, there's an, what looks like an extra shear web in the, in some of like the max cord region and stuff like that, just to make sure that you keep that part of the shell supported and then that structure rigid there. And in this design, they're removing that extra shear web and putting these closeout plates in there. And it is exactly like you guys say, the design looks like an airplane wing with a bunch of ribs in it. And to me, in my mind I'm, I'm not a, trained structural engineer, but from engineering principles and just kind of physics and forces and a little bit of knowledge there, this to me looks like it could solve some, some pretty big issues. However, in maintenance, that makes things a little bit more difficult because maintenance and construction, because it's harder to place these things in construction, of course, and to get them right. We already sometimes have a hard enough time placing shear webs and getting those right. Now you're adding perpendicular components and multiple ...

  • Why Are Australian Wind Farms Losing Money?

    Why Are Australian Wind Farms Losing Money?
    2024/11/05
    In this episode, Allen, Joel, Phil and Rosemary analyze why 38% of Australian wind farms are struggling with profitability despite stable PPAs. They explore how solar saturation, coal plant inflexibility, and maintenance contract structures impact returns. Plus, the team examines BlueFloat Energy's withdrawal from New Zealand and what recent auction results in Maine reveal about the broader challenges facing floating offshore wind development.

Pardalote Consulting - https://www.pardaloteconsulting.comWeather Guard Lightning Tech - www.weatherguardwind.comIntelstor - https://www.intelstor.comWind Energy O&M Australia Conference - https://www.windaustralia.com Allen Hall: It is almost fall. I guess it is fall. Joel Saxum: It's almost November. Allen Hall: I was just outside today. It was like 70 degrees outside. It felt like the end of summer, not the beginning of fall. But we're almost in winter. We got another month or two before we hit the official start of winter, which means all the bears up in my area are starting to thinking about hibernating. But in the meantime, they're usually pretty hungry, trying to fatten up before the winter really hits. And This causes a lot of problems if you're around bears, and a lady in Montana had a problem where she went out to work in her pickup truck early in the morning and realized that it had been all torn apart by a black bear, of all things, which is the thing that I worry about the most around here. At this time of year, when you're bringing in things from the house, and a bear shows up and says, Oh, there's groceries in the car, hops in, and then panics, which is what happened to this lady. The bear panics and just destroys the vehicle. And this has happened very close to us, actually. And not that long ago, it was this summer, where bears were walking in our driveway, walked right by my wife, she didn't even know it was there. So it's serious that don't leave your car doors open. That's the one thing I remember in the fall. Don't leave your car doors open for any length of time. Otherwise, when you go back, you may have befriended a bear. Philip Totaro: Allen, I've seen videos where they're opening car doors. So don't even think about, you can close the door and they're still gonna get in. So I don't know, man. They're getting sophisticated out there. Joel Saxum: I've got another tip for you from my childhood. You always put your trash out in the morning. Before your kids go to school, before you go to work, put your trash out in the morning on the street. Because if you put your trash out outside of your garage the night before, you're gonna end up with trash all over the ground and the garbage man won't pick it up and you, i. e. me, as a young child, would have to go pick up all of our trash multiple times. So that's the hot tip. Allen Hall: It's either the bears, the raccoons, or the wildcats. Those are the ones you really have to watch out for. Get a cat down in your neighborhood because it can do a lot of damage. Joel Saxum: You would think that Allen lived in like Northwest territories or something and not in Massachusetts. Allen Hall: I can walk out my back door and pet deer right now. That's how close they're sitting next to the house. Cause it's hunting season also where I am and all the deer join into town. They're hanging up. Yeah, there's, they're not stupid. Joel, he's in the Berkshires. This is the wilderness. This is about as wilderness as you can get in Massachusetts.

  • Avangrid Sells Kitty Hawk North, Saudi Arabia Localizes Towers

    Avangrid Sells Kitty Hawk North, Saudi Arabia Localizes Towers
    2024/11/04
    This week on Uptime News Flash, Avangrid sells the Kitty Hawk North lease area to Dominion Energy. In Saudia Arabia, the government signed two major localization agreements for wind energy steel towers. And Enerjisa Üretim has secured a major 1 billion 10 year term loan for the development of the YEKA 2 wind power plant. Welcome to Uptime News Flash. Industry news lightning fast. Your hosts, Allen Hall, Joel Saxum, and Phil Totaro discuss the latest deals, mergers, and alliances that will shape the future of wind power. News Flash is brought to you by Intelstor. For market intelligence that generates revenue, visit www.intelstor.com. Allen Hall: Well, Phil, Saudi Arabia has taken a significant step forward in its wind energy sector with the signing of two major localization agreements for wind energy steel towers. The agreements were signed by the Kingdom's Local Content and Government Procurement Authority with Al Yamama Steel Industries and Arabian International Company for Steel Structures. These deals are part of a large initiative that saw 107 agreements and memorandums of understanding signed during the Energy Localization Forum in Riyadh, valued at approximately 27 billion. I didn't realize there was that much money in steel towers, Phil, but wow. These agreements are impressive. Philip Totaro: Yeah, that that's for all agreements that they sign, not just the steel tower ones to, to clarify for everybody. But the, the interesting tidbit with this is the fact that, they obviously have a couple of, wind farms now in Saudi Arabia, one that's operational, one under construction, as well as a demo turbine from GE from, from a few years back. And they're, they're at a point where they're really looking at the future of renewable energy for themselves in, in their domestic market so that they can, have more control over, how much oil they export and, and where they export it to moving forward. So this gives them another knob to turn if they can use this renewable power for the power generation. Industry instead of leveraging their own oil abundant though it may be, they all recognize that there's a finite amount. So this is part of their efforts at domestication of part of the industry that they see as, as being an important element for them moving forward. So much so that their public investment fund has, has, Also made moves in the past to, put money behind renewable ventures in in Europe and Asia and even looking at the United States as well. So, this is them taking a step forward in terms of their renewable energy market. Joel Saxum: Yeah, Saudi Arabia keeps on basically reinventing itself and, and morphing into something that it wasn't in the past, which is very interesting. I, for one, I follow the, the Neom project very closely because it's really interesting to me. So they're spending a lot of money. I mean, they even went as far as to lure a lot of the PGA players away for their own golf league. And now they're setting up with Dana White from the UFC, they're setting up their own boxing league. So they're doing a lot of things. They're taking advantage of, of course, the money they have now to try and build what their economy is for the future. And, they have been a classically oil and gas economy. And, and that's where a lot of their sovereign wealth comes from. So they have the capabilities to make large structures and invest in, in, in industry. So going to steel towers for wind makes absolute sense for them. Allen Hall: Avangrid has successfully closed the sale of its Kitty Hawk North offshore wind lease area to Dominion Energy. The transaction was completed for 160 million dollars, comprising a lease acquisition payment of 117 million plus development cost reimbursement. While selling the northern section, Avangrade retains ownership of Kitty Hawk South, which has the potential to deliver 2. 4 gigawatts of power to North Carolina, Virginia,
